Lots of settings to configure the application just the way *you* would like. Separate settings for WiFi and mobile connections.

Backup and restore of app and account settings via Dropbox, OneDrive, Box.com, Google Drive.
This is the Lite version, which is limited to two accounts, no identities, and adds a promo signature to all outgoing messages with a link to the program’s web site.
You can add more than two accounts, use identities, and remove the promo signature by purchasing the Pro Unlocker app here on Play.
The app is available in (translated into) more than a dozen languages. Please see the web site for the list, a Google Play policy won’t let me include it here.
